Mac-Weld Seal Pots & Condensate Chambers – A106, CS & 316 SS

Mac-Weld seal pots and condensate chambers provide reliable liquid barriers for differential pressure measurement in steam and vapor systems. These vessels fabricated from A106 carbon steel or 316/L stainless steel seamless pipe protect instrumentation from process fluids. The units maintain constant liquid head on both sides of differential pressure transmitters for accurate flow measurement.

Additionally, schedule 40 or 80 seamless pipe construction ensures durability under pressure. Each unit features 3000 or 6000 lb rated ports with 1/2″ NPT connections as standard. All outlets come plugged with solid steel plugs for leak-free operation. Moreover, every seal pot includes hydrostatic testing for quality assurance.

Carbon steel units receive red or grey oxide primer finish for corrosion protection. Therefore, these seal pots excel in oil refineries, chemical plants, and pharmaceutical facilities. Consequently, they isolate instruments from corrosive or viscous process media while enabling accurate pressure measurement in steam applications.
